DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Reference will now be made in detail to the following exemplary embodiments, which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

The exemplary embodiments may be embodied in various forms without being limited to the exemplary embodiments set forth herein. Descriptions of well-known parts are omitted for clarity.

FIG. 1 is an architectural diagram of a network visualization system according to an exemplary embodiment. Referring to FIG. 1, network visualization system according to an exemplary embodiment may include client networks 1 through N 100, discovery/monitoring servers 1 through N 110, database/tracking servers 1 through N 120, databases 1 through N 130, and client (or “front end”) application 140, which includes workspaces 1 through N 150. The discovery/monitoring servers 1 through N 110 are responsible for querying actual devices in client networks 1 through N 100, respectively, and transmitting the results to the client application 140. The database/tracking servers 1 through N 120 are responsible for storing network topology, monitoring data, and device tracking, for the corresponding client network 100. Databases 1 through N 130 store data relating to the discovered devices and the client network 100.

Although in the exemplary architecture of FIG. 1 each discovery/monitoring server 110 is responsible for discovery and monitoring of its corresponding client network 100, the exemplary embodiment is not limited to one-to-one correspondence. Multiple discovery/monitoring servers 110 may be used to discover and monitor devices on a single client network 100, or a single discovery/monitoring server 110 may discover and monitor devices on multiple client networks 100.

The discovery/monitoring servers 110 may comprise a conventional general-purpose computer, a special-purpose computer, a distributed computer, or any other type of computer or server. The discovery/monitoring servers 110 may comprise one or more processors, such as a single central processing unit (CPU), or a plurality of processing units, commonly referred to as a parallel processing environment, which may execute instructions to practice the various aspects of the exemplary embodiments described herein.

Moreover, the discovery/monitoring servers 110 may be physical or virtual servers. For example, each discovery/monitoring server 110 may be a physically separate server, or multiple virtual servers may be contained within one physical device.

FIGS. 2A and 2B are block diagrams that further illustrate the structure of the client application 140 according to an exemplary embodiment. Client application 140 may be a local client residing on a user's workstation, or client application 140 may be web-based, allowing a user to access the application via the Internet. For example, client application 140 may be thin-client compliant, and may operate on a mobile device, table, etc. Referring to FIG. 2A, the client application 140 may include a discovery controller 141 and a DX renderer or rendering unit 142. The discovery controller 141 instructs the monitoring server 110 to perform discovery of devices on the client network 100. The discovery controller 141 receives the results of the discovery process and transmits those results to the DX renderer 142, which renders a visualization of the client network 100. The DX renderer 142 may render a visualization of client network 100 by itself, or in combination with one or more other client networks 1 through N 100. The DX renderer 142 may render the visualization of client network 100 using, for example, DirectX®, HTML5, or any other suitable visualization technique.

The DX renderer 142 may render the visualization as a stereoscopic representation of the client network 100. To provide a stereoscopic image, the DX renderer 142 may render two images—one for the user's right eye and one for the user's left eye—which the user's brain combines to give the appearance of a three dimensional (3-D) image. For example, DX renderer 142 may render the visualization using tune-sequential stereoscopy, in which the two images are alternately displayed; or spatial stereoscopy, in which the two images are displayed at the same time, with each image directed the appropriate eye of the user. In addition, the DX renderer 142 may render the stereoscopic visualization using a multi-layer liquid crystal display, as described in, for example, U.S. Pat. No. 8,259,242, the disclosure of which is incorporated herein by reference in its entirety.

The DX renderer or rendering unit 142 may include, but is not limited to, a software or hardware component, such as a Field Programmable Gate Array (FPGA) or an Application Specific integrated Circuit (ASIC), which performs certain tasks, and may include multiple processors. DX renderer may include, by way of example, components, such as software components, object-oriented software components, class components and task components, processes, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, microcode, circuitry, data, databases, data structures, tables, arrays, and variables. The functionality provided for in the components may be combined into fewer components or further separated into additional components.

Referring to FIG. 2B, the discovery controller 141 may include a data receiver 141 a and a discovery algorithm 141 b. The DX renderer 142 may include a rendering controller 142 a and a renderer 142 b. The data receiver 141 a receives a list of discovered devices from the monitoring server 110 and provides the list of discovered devices to the discovery algorithm 141 b, which generates a node graph mapping all of the discovered devices. The node graph is transmitted to the rendering controller 142 a of the DX renderer 142, which generates a point corresponding to each discovered device, and lines representing the connections between the discovered devices. The points and lines generated by the rendering controller 142 a are then transmitted to the renderer 142 b, which renders a visualization of the client network 100.

FIG. 3 is a flowchart of the discovery algorithm 141 b operating within client application 140 according to an exemplary embodiment. Referring to FIG. 3, the process begins at step 305 with the user setting the location of the monitoring server 110. Once the monitoring server 110 location is entered, a discovery wizard is shown in step 310, which includes various discovery parameters. For example, the discovery wizard may include various discovery modes such as, without limitation, CDP, Telnet, SSH, ARP, CAM, Ping, Routing, and DNS. In step 315, the discovery parameters are selected from the discovery wizard. In step 320, the discovery parameters are transmitted to the monitoring server 110 to start discovery. The process checks whether the monitoring server 110 is reachable in step 325. if the monitoring server 110 is not reachable in step 325, the process goes back to step 305, where the user sets the location of the monitoring server 110. If the monitoring server 110 is reachable in step 325, the process determines in step 330 whether there are newly discovered devices. If it is determined that there are no newly discovered devices in step 330, the process continues checking until a newly discovered device is detected. If it is determined in step 330 that a newly discovered device has been detected, the newly discovered devices are obtained in step 335. In step 340, only the newly discovered devices that do not exist in the current topology are selected. In step 345, the links between the newly discovered devices are found. At step 350, the links between the newly discovered devices and the existing topology are found. At step 355, the newly discovered devices and the found links associated with the newly discovered devices are added to the workspace for the client network. In step 360, the legend and attribute windows (described below) of the workspace are updated. At step 365, it is determined whether discovery is finished. If it is determined that discovery is not finished, the process reverts to step 330, where the process checks for newly discovered devices. If it is determined that discovery is finished in step 365, the discovery wizard is closed at step 370. In step 375, the discovery stats are shown describing information relating to the discovered devices, and the process ends.

The discovery process may be a partitioned discovery process in which discovery of multiple networks is performed simultaneously. A user is therefore able to centrally manage multiple networks more efficiently by discovering devices in each of the networks simultaneously.

FIG. 4 is a flowchart of the discovery process performed by the monitoring server 100 according to an exemplary embodiment. Referring to FIG. 4, when the monitoring server 110 receives a command to begin discovery from the client application, the process begins by determining in step 410 whether the discovery parameters have been received from the client application. If it is determined that the discovery parameters have not been received, the process continues to check until the discovery parameters have been received. If it is determined in step 410 that the discovery parameters have been received, the monitoring server 110 initializes a discovered devices list in step 420. In step 430, the monitoring server 110 determines which discovery method has been selected. If Telnet discovery has been selected, in step 440 one or more Telnet discovery threads are started with one or more initial addresses. If SNMP discovery has been selected, in step 450 one or more SNMP discovery threads are started with one or more initial addresses. The discovery threads perform actual discovery of specified IP addresses, as explained further below. After successful discovery of a network device, each discovery thread initializes other discovery threads to discover any neighboring devices. All discovered network devices are stored in the discovered devices list.

In step 460, the process determines whether all discovery threads are finished. If it is determined that all the discovery threads are not finished, the process continues checking until all of the discovery threads are finished. If it is determined that all of the discovery threads are finished in step 460, the list of discovered devices is sent to the client application in step 470, and the process returns to step 410.

FIG. 5 is a flowchart explaining the discovery threads initiated in step 430 of FIG. 4, according to an exemplary embodiment. Referring to FIG. 5, the monitoring server 110 reads from the discovery wizard an IP address of a device to be discovered in step 505. In step 510, it is determined whether a device with the same IP address as the read IP address exists, if so, the process ends. If a device with the same IP address does not already exist, in step 515 the login attempt variable is set equal to a particular value, for example 3, and the system attempts to login at step 520. The login attempt variable indicates the number of times the system will attempt to reach the login interface for a particular set of login credentials. At step 525, it is determined whether login was successful. If it is determined that login was not successful at step 525, the process obtains the next login credential from a loin attempts dictionary at step 530. In step 535, it is determined if the obtained next login credential has been attempted for the device. If the next login credential has not been attempted, the process attempts to login with the next login credential at step 520. If the obtained next login credential has previously been used to attempt to login to the device, the process determines in step 540 whether there are any more login credentials that have not been attempted. If there are no more login credentials to be attempted, the process ends. If it is determined that there are additional login credentials that have not been attempted, a new login credential is obtained in step 530 from the login attempts dictionary. If it is determined that login was successful at step 525, the process discovers a device on the network in step 545, as explained in more detail below. Once a device has been discovered in step 545, the discovered device is added to the discovered devices list in step 550. In step 555, a device neighboring the device discovered in step 555 is identified. At step 560, a new discovery process is initialed for the neighboring device. After the neighboring device has been discovered, it is determined whether the initially discovered device has any other neighboring devices at step 565. if no other neighboring devices are detected, the process ends. If it is determined step 565 that other neighboring devices exist, the process reverts to step 555 where another neighboring device is identified.

FIG. 6 is a flowchart explaining in more detail step 540 m which a device on the network is discovered according to an exemplary embodiment. Referring to FIG. 6, in step 605, the device type of the networked device is discovered. For example, the device type may include, for example, router, switch, server, etc. In step 610, the device name is discovered. At step 615, it is determined whether the user has enabled a setting that skips the discovery of devices having high CPU usage. If the user has enabled this setting, the device's CPU usage is determined at step 616. In step 617 it is determined whether the determined CPU usage is above a CPU usage threshold. If the determined CPU usage is above the CPU usage threshold, the discovery process for that device ends. Thus, by enabling this setting and selecting the CPU usage threshold, the user is able to avoid discovering devices with high CPU usage, in order to avoid creating problems within the network due to the extra CPU resources required for discovery. If it is determined in step 617 that the CPU usage does not exceed the CPU usage threshold, or if it is determined at step 615 that the user has not enabled the setting that skips the discovery of devices having high CPU usage, the process proceeds to step 620, where the model of the device is discovered.

The process continues at step 625, in which the processor ID of the device is discovered. In step 630, the version of the device's operating system is discovered. At step 635, the device interfaces are discovered, and at step 640 the device SNMP location is discovered. In step 645, the device SNMP contact is discovered, and the device IP routes arc discovered in step 650. The device's CDP neighbors are discovered in step 655, the device's BGP (Border Gateway Protocol) is discovered in step 660, the device's VRFs [Virtual Routing Field] are discovered in step 665, the devices's MPLS (Multi-Protocol Label Switching) is discovered in step 670, and the device's HSRP (Hot Standby Routing Protocol) is discovered in step 675. In this step, VRRP (Virtual Router Redundancy Protocol) and GLBP (Gateway Load Balancing Protocol) may also be discovered. In step 680, it is determined whether ARP (Address Resolution Protocol) discovery is enabled. If ARP discovery is enabled, the process discovers neighbors from ARP in step 685, and then determines if the device is a switch in step 600. If ARP discovery is not enabled, the process skips discovering neighbors from ARP in step 685 and verifies whether the device is a switch in step 690. If it is determined in step 690 that the device is not a switch, the process ends. If it is determined in step 690 that the device is a switch, port channel information is discovered in step 605. After the port channel information is discovered in step 695, the process ends.

FIG. 7 is a flowchart explaining in more detail the login process referenced at step 520 in FIG. 5 according to an exemplary embodiment. According to an exemplary embodiment, the login algorithm may use multiple credentials specified by the user in discovery parameters. In the case of a successful login, matching credentials are stored for future querying of the device.

Referring to FIG. 7, the login process begins at step 710, in which login credentials are obtained from the login attempts library. The obtained credentials are sent to the discovered device in step 720. In step 730, it is determined whether the login was successful. If it is determined at step 730 that the login was not successful, the process determines whether other credentials may be used in step 740. If it is determined in step 740 that other credentials may be used, the process returns to step 710. If it is determined at step 740 that there are no other credentials to be used, the process returns a “False” result in step 750, and the login process ends. If in step 730 it is determined that the login process was successful, the process returns a “True” result in step 760 and the login process ends.

In addition to discovering network devices, the discovers/monitoring server 110 may also monitor the devices discovered in client network 100. the client application 150 is capable of directing the monitoring server 110 to perform various types of monitoring. For example, FIG. 8 is a flowchart describing a process of monitoring states of discovered BGP neighbors according to an exemplary embodiment. in the exemplary embodiment, the monitoring server 110 performs querying of the discovered device, and the results may be transmitted to the client application 150 at predetermined times, time intervals, or any other time. When the state of a BGP neighbor is updated, a line or other object in the workspace 140 representing the updated BGP neighbor flashes, or provides some other indication of the update.

Referring to FIG. 8, the user of the client application 150 starts BGP monitoring at step 805. In stop 810, the client application 150 connects to the monitoring server 110. In step 815, it is determined whether the monitoring server 110 is reachable. If it is determined that the monitoring server 110 is not reachable, the BGP monitoring process ends. If it is determined at step 815 that the monitoring server 110 is reachable, a new monitoring session is started on the monitoring server 110 at step 820. In step 825, existing BGP records are added to the new session. At step 830, it is determined whether an update interval has elapsed. If the update interval has elapsed, the process proceeds to step 835, where the client application 150 obtains updated session records from the monitoring server 110. If it is determined at step 830 that the update interval has not elapsed, the process continues checking the update interval until it has elapsed. At step 840, a BGP record is selected from the attribute list of the workspace 140 for client network 100. In step 845, a corresponding record is located by the monitoring server 110. The BGP record selected from the attribute list is then updated in in step 850 using the corresponding record located in the monitoring server 110. At step 855, an indication representing the updated record is flashed on the workspace 140. The indication may be any type of visual or other type of indicator. In step 860, it is determined whether the attribute list includes any other BGP records. If it is determined that the attribute list does not include any other BGP records, the BGP monitoring process ends. If it is determined at step 860 that the attribute list includes other BGP records, the process returns to step 830, where it is determined if the update interval has elapsed.

FIG. 9 is a flowchart illustrating another type of monitoring, HSRP monitoring, according to an exemplary embodiment. In the exemplary embodiment, the states of discovered virtual IP addresses (VIPs) are monitored. The monitoring server 110 performs querying of the discovered device, and the results may be transmitted to the client application 150 at predetermined times, time intervals, or any other time. When the state of a VIP is updated, an icon in the workspace 140 that represents the updated VIP flashes, or provides some other indication of the update.

Referring to FIG. 9, the user of the client application 150 starts the HSRP monitoring process at step 905. At step 910, the client application 150 connects to the monitoring server 110. At step 915, it is determined whether the monitoring server 110 is reachable. If the monitoring server 110 is not reachable, the HSRP monitoring process ends. If it is determined at step 915 that the monitoring server 110 is reachable, a new HSRP monitoring session is started at step 920 on the monitoring server 110. In step 925, existing HSRP records are added to the new session. At step 930, it is determined whether an update interval has elapsed. If it is determined that the update interval has not elapsed, the process continues checking the update interval until it has elapsed. If It is determined at step 930 that the update interval has elapsed, the process proceeds to step 935, where the client application 150 obtains updated session records from the monitoring server 110. At step 940, an HSRP record is selected from the attribute list of the workspace 140 for client network 100. In step 945, a corresponding record is located by the monitoring server 110. The HSRP record selected from the attribute list is then updated in in step 950 using the corresponding record located in the monitoring server 110. At step 955, an indication representing the updated record is flashed on the workspace 140. The indication may be any type of visual or other type of indicator. In step 960, it is determined whether the attribute list includes any other HSRP records. If it is determined that the attribute list does not include any other HSRP records, the HSRP monitoring process ends. If it is determined at step 960 that the attribute list includes other HSRP records, the process returns to step 930, where it is determined if the update interval has elapsed.

FIG. 10 is a flowchart illustrating a process of monitoring states of the discovered devices according to an exemplary embodiment. In the exemplary embodiment, the process may monitor, without limitation, one or more of interface loads, route count, memory used, available memory, CPU usage, uptime, and TCAM count. The monitoring server 110 performs querying of the discovered device, and the results may be transmitted to the client application 150 at predetermined times, time intervals, or any other time. When the state of a discovered device is updated, an icon in the workspace 140 that represents the updated device flashes, or provides some other indication of the update.

Referring to FIG. 10, the user of the client application 150 starts the device monitoring process at step 1005. At step 1010, the client application 150 connects to the monitoring server 110. At step 1015, it is determined whether the monitoring server 110 is reachable. If the monitoring server 110 is not reachable, the device monitoring process ends. If it is determined at step 1015 that the monitoring server 110 is reachable, a new device monitoring session is started at step 1020 on the monitoring server 110. In step 1025, existing device records are added to the new session. At step 1030, it is determined whether an update interval has elapsed. If a is determined that the update interval has not elapsed, the process continues checking the update interval until it has elapsed. If it is determined at step 1030 that the update interval has elapsed, the process proceeds to step 1035, where the client application 150 obtains updated session records from the monitoring server 110. At step 1040, a device record is selected from the attribute list of the workspace 140 for client network 100. In step 1045, a corresponding record is located by the monitoring server 110. The device record selected from the attribute list is then updated in in step 1050 using the corresponding record located in the monitoring server 110. At step 1055, an indication representing the updated record is flashed on the workspace 140. The indication may be any type of visual or other type of indicator. In step 1060, it is determined whether the attribute list includes any other device records. If it is determined that the attribute list does not include any other device records, the device monitoring process ends. If it is determined at step 960 that the attribute list includes other device records, the process returns to step 1030, where it is determined if the update interval has elapsed.

FIG. 11 is a flowchart illustrating a process of monitoring interfaces of the discovered devices, or links between discovered devices, according to so exemplary embodiment. In the exemplary embodiment, the process may monitor links between discovered devices to detect changes in the network topology. The monitoring server 110 performs querying of the discovered device, and the results may be transmitted to the client application 150 at predetermined times, time intervals, or any other time.

Referring to FIG. 11, the user of the client application 150 starts the link monitoring process at step 1105. At step 110, the client application 150 connects to the monitoring server 110. At step 1115, it is determined whether the monitoring server 110 is reachable. If the monitoring server 110 is not reachable, the link monitoring process ends. If it is determined at step 1115 that the monitoring server 110 is reachable, a new link monitoring session is started at step 1120 on the monitoring server 110. In step 1125, existing device link records are added to the new session. At step 1130, it is determined whether an update interval has elapsed. If it is determined that the update interval has not elapsed, the process continues checking the update interval until it has elapsed. If it is determined at step 1130 that the update interval has elapsed, the process proceeds to step 1135, where the client application 150 obtains updated session records from the monitoring server 110. At step 1140, a device record is selected from the attribute list of the workspace 140 for client network 100. In step 1145, a corresponding record is located by the monitoring server 110. The links in the device record selected from the attribute list are then updated in in step 1150 using the corresponding record located in the monitoring server 110. At step 1155, a line representing an updated link on a workspace is flashed or otherwise indicates that the link has been updated. In step 1160, it is determined whether the attribute list includes any other device records. If it is determined that the attribute list does not include any other device records, the link monitoring process ends. If it is determined at step 1160 that the attribute list includes other device records, the process returns to step 1130, where it is determined if the update interval has elapsed.

FIG. 12 is a flowchart illustrating a process of latency monitoring, according to an exemplary embodiment. In the exemplary embodiment, the process may monitor latencies between any pair of discovered devices. The monitoring server 110 performs querying of the discovered devices, and the results may be transmitted to the client application 150 at predetermined times, time intervals, or any other time. When the latency between any pair of discovered devices is updated, one or more icons in the workspace 140 that represent the latency and/or the discovered devices flashes, or provide some other indication of the update.

Referring to FIG. 12, the user of the client application 150 starts the latency monitoring process at step 1205. At step 1210, the client application 150 connects to the monitoring server 110. At step 1215, it is determined whether the monitoring server 110 is reachable. If the monitoring server 110 is not reachable, the latency monitoring process ends. If it is determined at step 1215 that the monitoring server 110 is reachable, a new latency monitoring session is started at step 1220 on the monitoring server 110. In step 1225, existing latency records are added to the new session. At step 1230, it is determined whether an update interval has elapsed. If it is determined that the update interval has not elapsed, the process continues checking the update interval until it has elapsed. If it is determined at step 1230 that the update interval has elapsed, the process proceeds to step 1235, where the client application 150 obtains updated session records from the monitoring server 110. At step 1240, a latency record is selected from the attribute list of the workspace 140 for client network 100. In step 1245, a corresponding record is located by the monitoring server 110. The latency in the device record selected from the attribute list is then updated in in step 1250 using the corresponding record located in the monitoring server 110. At step 1255, an indication representing the updated latency record is flashed on the workspace 140. The indication may be any type of visual or other type of indicator. At step 1260, it is determined whether the attribute list includes any other latency records. If it is determined that the attribute list does not include any other latency records, the latency monitoring process ends. If it is determined at step 1260 that the attribute list includes other latency records, the process returns to step 1230, where it is determined if the update interval has elapsed.

As the devices in the client network 100 are detected and/or monitored, the DX renderer 142 performs a rendering algorithm to visualize the client network 100 and its discovered devices in workspace 140. By rendering the visualization of the client network 100 as the results of the discovery and/or monitoring process are obtained, the user is able to graphically view changes to the network and/or the networked devices in real-time.

FIG. 13 is a flowchart illustrating a rendering algorithm executed by the DX renderer 142 according to an exemplary embodiment. Referring to FIG. 13, the rendering algorithm of the exemplary embodiment begins at step 1305 with the selection of a DX workspace. Once a DX workspace has been selected, it is determined in step 1310 whether the DX workspace is initialized. If it is determined in step 1310 that the DX workspace is not initialized, the selected DX workspace is initialized in step 1315, and the process proceeds to step 1320. If it is determined in step 1310 that the selected DX workspace is initialized, the process proceeds to step 1320. In step 1320, it is determined whether the DX workspace requires resizing. It is determined that the selected DX workspace needs resizing, the process recreates the necessary resources and adjusts the size of the workspace in step 1325, and the process continues to step 1330. If it is determined in step 1320 that the selected DX workspace does not require resizing, the process proceeds to step 1330.

In step 1330, the DX renderer renders the detected devices. In step 1335, the DX renderer renders the connectors between the detected devices. In step 1340, the DX renderer renders captions for the rendered detected devices and connectors. In step 1345, the DX renderer renders flashes or other indications representing that the network, the detected devices, or some aspect of the network or detected devices, e.g., latency, has been updated. In step 1355, it is determined whether a zoom region of the workspace 140 is active, if it is determined that the zoom region is active, the DX renderer renders the zoom region at step 1360, and the process continues to step 1365. If it is determined in step 1355 that the zoom region is not active, the process continues to step 1365. At step 1365, it is determined whether the workspace 140 is closed. If it is determined that the workspace 140 is closed, the rendering process ends. If it is determined in step 1365 that thee workspace 140 has not been closed, the process reverts to step 1320, where it is determined whether the workspace requires resizing.

According to an exemplary embodiment, client application 150 allows the user to select from numerous workspaces 100, so that the user is able to visualize many different client networks 100. According to an exemplary embodiment, the DX renderer may utilize Direct X to perform rendering.

For example, if a user knows that a problem occurred on the network at 1:30 pm, the user could search the indexed traffic data by timestamp to determine which packets transmitted on the network may be associated with the problem. The results of the search may then be rendered by DX renderer 142. For example, the results of the search may be graphically rendered in a geographic representation showing the physical location of the source and/or destination of an indexed packet or communication.

The client application 140 may also provide a service desk interface for users to submit requests for additional visualization features. For example, the client application may allow the user to type a description of the visualization feature the user desires to be implemented. Requests may be submitted privately, or the requests may be displayed on the main window layout of FIG. 14 or the molecule window layout window of FIG. 15. The display window may include a description of the requested feature and a status indicator that indicates the development status of the requested feature.
